T 0 all whom it may concern:

Be it known that I, CLARENCE E. STEERE, a citizen of the United States,. residing at Chicago, in the county of cook-and State of Illinois, have invented certainbnfew and useful Improvements in {Embessi iig-Maehines, of which the followi'ng lisifaspecification.

My invention relates to improvements in stamping or embossing machines and has more particular reference to improvements in machines of this character for stamping or striking up letters or other printing characters on such material as sheet metal to be used as so-called printing'plates for addressing machines and the like.

One of the objects of my invention is to provide a machine of this character which will be simple, durable and reliable in construction'and e'fi'ective and eflicient in operation.

Other objects of my invention will appear hereinafter.

Referring to the accompanying drawings: Figure 1 is a view in side elevation of a machine embodying my invention; Fig. 2 is a plan view of said machine; Fig. 3 is a vertical longitudinal section of the machine taken substantially on the line 33 of Fig. 2; Fig. 4 is a transverse vertical section taken substantially on the line H of -Figs. 2 and 3; Fig. 5 is a staggered detail section sub stantially on the line 55 of Fig. 4; Fig. 5 is a detail section on the line 5 5 of Fig. 5; Fig. 6 is a transverse vertical section substantially on the line 66 of Fig. 3; Fig. 7 is an enlarged detail section substantially on the line 7-7 of Fig. 3; Fig. 8 is a detail view in elevation of the die-carrying or embossing wheels and the mechanism for actuating them; Fig. 9 is an enlarged detail view, partly in section, of the escapement mechanism and associated parts shown in the upper part of Fig. 5; Fig. 1 0 is a detail view of the mechanism shown in Fig. 9, this view being taken substantially on the line.

. perspective of the escapement dog; Fig. 14

is a'detail fragmentary view of a portion of one of the die-carrying wheels; 15 is a detail section on line 15-15 of Fig. 3, and

F ig. 16 is an enlar ed perspective of the cams for operating t e die-carrying wheels.

The machine shown in the drawings and which illustrates oiie'embodiment of my invention, has been designed more particularly forthe purpose of embossing or raising letters or other printing characters from small plates or strips of sheet metal such as r are used as printing plates in connection with addressing machines and the like. It will be obvious, however, to one skilled in the art, after having obtained an understanding of my invention from the disclosures herein made, that the machine may be modified or used for operating upon other materials without departing from the scope and spirit of the invention, and I wish it to be so understood;

My invention will be described in connection with the particular machine shown in the drawings. A description of the printing plates is unnecessary except to say that in this particular instance they are made of flat sheet metal rectangular in shape and the letparts and mechanisms are'mounted in compact operative relation in a substantial sup- .porting frame Bso as to form a complete operating unit which may, if desired, be readily carried about. The printing plates upon which .the letters or other printing characters are to be embossed are adapted to be positioned between two rotary die-carrying or embossingwheels C. These die-carrying wheels are located preferably in the front portion of the frame adjacent the keyboard so that the operator may at all times observe the work of the machine, thus giving the advantage of making this machine a socalled visible machine. Each embossing. wheel or member C has an outstanding annular flange or rim 1, so to speak, inwhich a plurality of radial slots are out, the number of these radial slots corresponding preferably to the range of letters or printing char acters which the machine is designed to emaged.

- to readily read the letters on the upper face of the printing plate A while said printing plate is in position. In this manner the stamped or embossed words on the printing plate will read in regular order instead of backward and the operator can thereby observe at all times just what letters are being stamped. upon the plate. The stamping dies 2 are comparatively short and their inner ends rest upon the edge or outer periphery 3 of a thrust ring or plate which is set into the front face of each of the (lie-carrying wheels. A clamping ring 4 is then fastened or bolted to the front face of the tlange 1 to hold the dies in place. This construction serves to rigidly hold the dies in their proper position and at the same time permit any one or more of the dies to be readily removed or replaced in case they become damlhe two die-carrying wheels C are preferably identical in construction and are peripherally opposed one above the other or in edgewise relation, preferably so that they lie in practically the same vertical plane when they are in embossing position. They are mounted upon and driven by the shafts 6 and these shafts are journaled in comparatively long bearings or mountings 7. These bearings each have at their inner ends trunnions 8 which are mounted upon pivot studs 9. These studs are supported on the side members i of the frame. They terminate short of each other to provide a space therebetween and are axially alined. They form 'a common pivotal aXis about which the diecarrying wheels C and bearings 7 can be bodily swung or rocked. The pivot studs 9 and .the die-carrying wheels C are arranged in such position that the axes of rotation of the wheels C lie in a plane which passes through or includes the point in which the complementary dies on the die wheels meet, hence said plane is perpendicular to the vertical plane in which the die-carrying wheels lie when said die-carrying wheels are closed together and in their embossing or stamping position. The printing plate A is adapted to be positioned by means of the carriage, later to be described, in this plane which includes the axis of the pivot studs 9, as shown clearly in Fig. 8. By this construction and arrangement of the parts, of rourse the die-carrying wheels necessarily rim aces line which is so close to a vertical line at right angles to the plane of the printing plate that practically no lateral movement will be imparted to the plate or the metal thereof during the actual compression of the plate between the two dies. Tomake this clearer it will beobserved that for a short distance above and below the printing plate A the curvature of the arc in which the opposed or complementary dies on. the die-carrying wheels move is so negligible as to practically amount to a straight vertical line, hence the dies will approach and recede from the printing plate on' a vertical line which is practically exactly at right angles to the plane of the plate, thereby eliminating any errors or inaccuracies'which would occur if the dies were not arranged. so that they would move in a vertical line. die-carrying wheels are separated need in practice be just suilicient to permitthe coin venient insertion or removal of the printing plate A. The bodily movement of both of the die wheels also has the advantage of readily stripping with respect to the plate A that is to say, the dies of'both wheels posi-- tively move entirely clear of the plate A after each embossing operation and hence cannot stick to the plate.

The inner or rear ends of the die wheel shafts 6 carry gear wheels .0 (Figs. 1, 2, 3 and 8) which are identically alike and of the same size and which mesh with and are driven by an intermediate or common gear 11 positioned therebetween. Referring more particularly to Figs. 1 and 3, it will be seen that the intermediate gear 11 is rotatably The distance to which the till mounted upona long main shaft 12 of the machine. The forward end of this shaft is journaled in a bearing 13 which is positioned, as will be seen, just in the rear of the die-carrying Wheels C, and the rear e d of v the shaft is journaled in a similar hearing The iorward bearing 13 is'formed on a 14-. bridge member 15 of. necessary strength which, as shown 111' Fig. 2, spans the two side members of the irame B. The longitudinal axis of the main shaft also lies in the plane which passes through the axis of pivots 9 and the printing plate A. This shaft preferably driven constantly in any suitable manner. In the construction shown the rear-end of the shaft carries a large fly-wheel 16 which can be driven by a, belt from an electric motor or other source of power (not shown). The gear 11 drives the gears 10, and through the medium of the shafts 8, the die-carrying wheels are given their rotany motion. It will be noted that the 4 1,17aeea carrying wheels are thus rotated in the same direction; that is to say, the portions of.

obvious, because while one die-carrying wheel may have the tendency to carry the operators fingers in between the wheels the other die-carrying wheel has an equal tendency of throwing out the finger so that in practice I find it almost impossible for the operator to become injured. The train of gears for driving these parts, comprising the individual gears 10 and the common intermediate gear 11 are. all arranged in a substantially vertical plane which passes through the axis of the pivots 9. As before mentioned, and as shown in Fig. 8, the

die-carrying wheels need only be separated just a sufiicient amount to allow the convenient insertion or removal .of the printing plate A. While the opening and closing of the die-carrying wheels about the pivots 9 as a' common axis shifts the gears 10 slightly laterally with respect to the. intermediate gear 11 this movement is so negligiblethat no special provisions need be made. Just in the rear of the forward bearing of the main shaft. this shaft has a squared portion 17 on which a thimble 18 is mounted so as to be rotated by the shaft but slidable longitu dinally of said shaft. A sleeve 19 surrounds the thimble 18 and moves'longitudinally with said thimble 18. The sleeve, however,

is fixed against rotation as will later appear.

19 is a toggle, each toggle comprising two links 21 (see Fig. 8). The two links of each toggle are pivoted together and pivoted to the sleeve 19 at 22 to form the knuckles of the toggles, and as above intimated, the toggles thus hold the sleeve 19 against rotation. The other ends of the respective toggle links are ivo-tally connected at 23 to the rear ends of t e levers 25. These. operating levers 25 see Figs. 2, 3 and 8) are pivoted at 26 to the frame of the machine and their forward ends are pivotally connected at 27 to the bearings 7 which carry the die-carrying wheels. sleeve 19 are moved forward longitudinally along the main shaft 12 thetoggles will tend to straighten out and will rotate the operat- Thus when the thimble 18 and .mg levers 25 about their pivots, and these levers in turn will actuate the bearings 7 and the die-carrying'wheels to close them together and make the impression upon the printing plate A positioned therebetween.

It will be noted that there is a set of operating levers and toggles on each side of a vertical plane passing through the longitm dinal axis of thedie-carrying wheel shafts 6 so that the power for actuating each diecarrying wheel is applied at two points (the pivots 27 of the operating levers 25) which are spaced apart a considerable distance laterally, and in consequence the power will be applied in a balanced condition and all tendency of the shafts 6 and bearings 7 to spring laterally is practically eliminated. The operating levers 25 are connected to-the bearings 7, through the medium of the pivthe die-carrying wheels in practically a ver tical plane which is almost coincident with the vertical plane in which the die-carrying wheels lie. In other words,,by means of this constructionthe power is applied to the diecarrying wheels almost directly at the points where they meet and make the impression upon the printing plate.- This insures a powerful direct actuation of the die-carrying wheels by means of the toggle system of levers. The power applied to move the sleeve 19 and thimble 18 is-greatly multiplied through this system of levers and the die-carrying wheels will be powerfully actuated.

The inner or rear end of the thimble 18 (see Figs. 2, 6, 7, 8 and 16) carries an annular cam E which is the exact counterpart of a similar cam F secured to theend of the gear 11-. Both of these cams have corresponding high parts E and. F and low parts E .and F respectively,'these high and low parts being preferably arranged so that they occupy equal portions of the circle in which the cam is disposed. In other words, they are constructed so that the high part of one cam fits the low part of the opposed cam. Hence, when the cams are rotated relatively the high parts of one cam ride up on the high parts of the other cam and a relative longitudinal movement of the cams will take place. This is the manner in which longitudinal movement is imparted to the thimble and sleeve 19, for actuating the toggles to close the die-carrying wheels, as previously described. I

I As before mentioned the cam F is fastened to the gear 11 for rotation therewith andthe power for driving the gear 11 is derived from the main shaft 12 through the medium of the thimble 18 and the two cams E and F. 7 That is 'a' say,whenthe cams are in such-position that the high parts of each cam occupy a position within the low parts.

or intermediate gear 11 and since there is no load to speak of on these parts very little power is required to rotate them. In consequence, therefore, the friction between the two cams, when their high and. low parts are interfitted, is sufiicient to drive the discarrying wheels but as a further precaution I provide means for locking the twocams together. In the structure shown this look consists of a dog 30 (see FigsltG, 7 and 16) one end of which is fastened in the end of a shaft 31 which-passesthrough the cam F and gear 11, and the other end of which is adapted to engage one ofj'the notches or teeth 32 in the cam E. Theteeth 32 are formed on theinner periphery of the cam .E at points corresponding to the centers of the high. parts E of said cam. The end'of the dog 30 occupies a position corresponding to the center ofone of the low parts F of the cam F. Thus when the high and low parts of the cams register with each other, such as shown in Fig. 8, the dog 30 will bein position to engage one of the teeth 32 of the ca nAE and thus lock the cams together.

The main shaft 12 is preferably constantly rotated, hence when the two cams are in register the die-carrying wheels will likewise be rotated. The two die wheels will continue to rotate until one of the cams is" stopped so that a relative rotation of the two cams will take place.

plementary dies on said wheels is accomplished through the medium of a series of stop devices corresponding to the letters or other printing characters on the die-carrying wheels.

The gear 11 carries a comparatively long' outstanding substantially radially disposed arm 35 which rotates with the gear 11 and which sweeps around in a vertical plane just in front of a large fixed disk or member G. The shaft 31 on which the dog-'30'is mounted also has a substantially radially disposed arm 36. This arm ispositioned adjacent the arm 35 but it is normally held at an angle to the face 37 of thearm- 35 by means of a light curved spring 38.

3 row are equally spaced apart and the pi 12 and through the'axis .of the pins on t -e keyboard arrangement.

In the machineshown this control of the die-carrylng I wheels and the selection of the proper com- -tioned in substantially the same horizon I This spring thus yieldingly holds the dog in en-- room for the main shaft. This member '1 carries-a plurality of stop pins i0 which 1 adapted to be projected into the path of revolving arms 35 and 36. Referring to '6 it will be noted that these stop pins a preferably arranged in two annular co centric series of rows. The pins in ea-v of the inner row are staggered with res to those of the .outer row or series so tn 3 radial lines drawn from the axis of the she J inner rows will pass midway between the pins of the outer row. The number of pi in these series correspond to the number printing characters on the die-carrying 7 wheels so that each pin represents a corre sponding letter or printing character on the die-carrying wheel. They are so positioned with respect to the dies inthe die-carryi wheels that each pin will operate to st the die-carrying wheels in position to st or emboss the printing character which represents on the plate A. Each one of th pins are operated by a key H positio preferably in the lower forward end of 5/ frame,- all of the keys being arrange suitable keyboard form similar to a lino machine or a typewriter or any stan Each of the pins 40 is carried in small bushings i]. win are set in corresponding holes in the men" ing plate G so that the pins maybe re? removed or replaced individually. E pin is surrounded by a coil spring 42 whi yieldingly holds the pin. with its 'fOl'Y end flush with the front faces 43 of the i G and hence out of the path of the arms and'36. The rear end of each stop pin is the other end of which is connected at to the rear end of a key-lever 4-8.

The key-levers 48 are preferably all 138151:

plane in the lower part of the frame of on machine and they are all pivoted upon transverse shaft or pivot member 49. forward ends 50 of the key-levers are upturned and positioned in the proper A board arrangement. They carry the t buttons H for convenient operation. it will be seen that when the operator pr the key H, the corresponding stoppin be projected forward into the path oi rotating arms 35 and 36 and will st rotation of said arms, thus holding the 11 and the cam F against rotation.

of course, stops the gear wheel 10. and sequently the'die-carrying wheels 31. in tion so that when said die-carrying are brought together they will stamp oi upon the plate A. The rotatin of course strikes the projected pin 41 first boss the corresponding printing character arm 36,

and the inomentumnof the parts will cause this arm to be rotated until it abuts the face 37 of the arm 35, as shown in dotted lines in Fig. 7. The slight relative rotation of the 36 throws the dog clear of the tooth '32 and unlocks the cams and the cam F is thus held against rotation but the cam B, being driven by the main shaft, continues to rotate and its high parts E ride on the high parts F of the cam F. This operation of course moves the thimble 18 and sleeve 19 longitudinally forward, and through the 'medium of the toggles and levers previously described brings the two die-carrying wheels together with a powerful pressure in exact alinement so that they will register perfectly and emboss a clean perfect letter on the plate A. No lost motion or play must be allowed between the die-carrying wheels during this actual stamping operation, and in consequence I provide an alin ing mechanism which exactly positions the die-carrying wheels with respect to each other as they come together.

Referring. more particularly to Figs. 3 and 14, it will be observed that the rear faces Qof the die-carrying wheels are pro-' vided with a series of. radial slots 60, each slot of which corresponds exactly in relative position to an embossing die 2 on-the wheel.

Just above and below the stamping position,-

that is the plane, in which the plate A lies, is a pair of alining pins 61 (seeFig. in the forward end portions of these pins are journaled bushings 62 which are eccentrically mounted in the ends of suitable sockets orbores 63 in the frame. These pins have enlarged heads 64 at their rear ends which are slidable in the bores 63 and between these heads 64 and the bushings 62.

are coil 'springs 65 acting to ,yieldingly hold the forward ends of the pins substantially flush with the ends of the bushings, that is to say the springs tend to hold the alin ing pins 61 out of the path of the die-carry ing wheels C. The rear ends of the pin 64: abut against the end of the sleeve 19, and when the sleeve 19 is moved longitudinally forward the pins are likewise moved and their forward endsprojected into the slots 60 in the rear faces of the die-c 'rrying wheels. The alining pins 61 are slightly tapered at their ends and the edge portions of the walls of the slot 60 are beveled as at 66 so that the pins will properly enter the alining slots 60 and slightly move the diecarrying wheels into exactly alinedposition in the event that they should be slightly outv of position. alining pins are positioned very close to the point Where the impression is made upon It will be noted that these the plate and in consequence eliminates all chance of errors or inaccuracies. The alining pins are so timed with respect to the other parts that they begin to move toward I the alining slots 60 just after the dog 30 has been released from engagement with the tooth 32 of the cam E so'that the die-carry- -ing wheels have actually come to a dead stop before the alining pins enter said alining slots. In a machine of this character it is desirable to remove the stopping pin 40 from the path of tlie rotating arms after the arms have been stopped and while the operation of making an impression upon the plate A is being performed. In the structure shown in the drawings I withdraw the stop pins ll by actuating the particular keylever which is depressed. In the forward part of the frame B beneath the key-levers is a transverse shaft 67 and this-shaft carries a common or universal bar 68 which 1s adapted to be rotated in and out of engagerotated; This bar normally occupies a posi'-' ment with the key-levers when the shaft is tion below the key-levers, that is out of the path thereof, so as to permit theirdepression. It is yieldingly held in this position by a suitable spring 69, one end of which is anchored to the frame-of the machine and the other end to a'small arm 70 on the shaft 67 (see Figs. 3, 4 and 5). Substantially beneath the operating toggles is a long transverse shaft 71 journaled in the frame of the machine and this shaft carries two arms 71 and 74 rigidly connected therewith. The arm 7 2 is pivotallyconnected at its upper end to a lug 73 on the longitudinally movable sleeve 19 (see Figs. 8 and 15).

The arm 74 extends downwardly tothe lower part of the frame and is given a horizontal turn at its lower end 75 and this end is connected by a link 76 to the short arm 70 on the transverse shaft67, thus when the thimble 18 and sleeve .19 are moved forwardly the arms 71 and 74: and shaft 71 are rotated,.thus rotating the universal bar 68. This bar acts upon the under side of the particular key-lever which has been depressed and restores the lever to its original posi tion. The movement of the key-lever of. course withdraws the stop pin 41 from the path of the rotating arms 35 and 36. These parts are u inc-Si that the'endof the stop pin 41 is not completely withdrawn from engagement with the arm 36 until the diecarrying wheels have just made their impression upon the plate A. The arm 74: is connected with the link 76 by means of a lost motion connection so that when the arm 74 moves rearwardly it will pull'on the link 76; and rotate the universal bar, but when the arm 74: moves in the opposite direction during the vrestoration of the parts it will move relatively to the link and will not thereby actuate said link and universal bar. Any suitable connection be provided at this point. shown, the end 75 of the arm 74: has an opening'or hole through which the link 76 extends. The end or" the link 76 carries a nut 77 which is engaged by the end 7 5 of the arm during its rearward movement.

This arrangement also provides an adjustment whereby the proper position of universal bar may be properly determined.

Fig. 3 shows the die-carrying wheels on the point of being restored. in this condition of the parts the pin 4-1 has just been completely withdrawn and the key-lever restored. Since the pin ll is now out of the path of the rotating arms 35 and 36 the arm 36 is relatively rotated slightly by its spring 38 which restores the dog 30 to a position where it will engage the teeth on the cam E when said cams again register.; The withdrawal of the stop pin releases the arms 36 and 36, the gear 11 and cam F from said stop pin 41 but the cam F and gear 11 cannot as yet rotate for the reason that the alinement pins hold the die-carrying wheels against rotation, thus holding the gears 10 and intermediate gear 11. Since the main shaft 12, however,'is constantly rotating, the cam E will continue its rotation and its high parts will ride down, so to speak, into the low parts of the, cam F and at the same time the thimble 18 will \move longitudinally rearward under the action of the springs which surround the alinement pins 61. At the same time the toggles are gradually collapsed and the levers which they operate will swing or rock the die-carrying wheels apart. These parts all operate in proper timed relation and by the time the two cams E and F again register the alinement pins will be withdrawn and the die-carrying wheels swung completely open,

The timing of these parts is such that the p alinement pins will be withdrawn from the alinement slot 60 slightly before the cams reach a complete registering position. This unlocks the die-carrying ,wheels and the parts connected therewith and leaves them free to be rotated slightly before the cams actually reach their complete registering position. The friction incident to the pressure i '(caused by the springs 65) ofthe cam E upon the cam F will then co ns into play to In the construction amassestart the die-carrying wheel rotating. There other rotating parts and in consequence the friction between the two cams will gradu ally start the die-carrying wheels and rotating parts. That is to say, after the alinement pins have been withdrawn there will still be a relative slip between the two cams before the cam E completely registers with" the cam F, and during this slight relative slip the friction between the two cams starts the rotation of the die-carrying wheels and gradually brings them up to speed, thus avoiding sudden strains or blows on the parts. By the time the two cams completely register the die-carrying Wheels will be fully up to speed, and the dog 30 being positioned by the spring 38, will engage one of the teeth 32 of the cam E and lock the cams togc-ther again. It will be noted also that in stopping the rotation of the die-carrying wheel a cushion effect occurs when the arm 36 strikes the projected pin. This is obvious for the reason that the blow which the arm strikes the pin-is counteracted by the spring 38 during time the dog 30 is being disengaged from the cam E and also while the cam E rides up on the high parts of the cam F.

Since the arms 35 and 36 are normally at an angle with respect to each other and hence spaced apart during their rotation there is a possibility that the operator might depress a key and project one of the stop face of the arm 35 with two slots 35. These slots are deep enough 'so as to permit the arm 35 to pass over the stop pin in the event that said stop pin should be projected into the space between the two arms 35 and 36. The rotating arms will thus pass said pins without being stopped thereby until they have made one complete rotation and again arrive in proper position with respect to the projected stop pin.

The plate A is removably mounted in a suitable carriage K so that it may be moved in, both directions for line spacing and letter spacing of the printing characters. This carriage in the structure shown comprises a long narrow rectangular open frame which is adapted to slide or shift longitudinally of itself in a pair of guideways 80. These rat 7 guideways are connected at theirends by transverse to the longitudinal direction of movement of the carriage K for spacing the are lines of printed characters on the plate.

The connecting bars 81 of the sub-carriage are mounted to slide 1n this direction in suitable guideways or members 82 fastened to pi'inted characters on the plate may be ac- -nection with Fig. 11.

ornplished in any suitable manner, such for instance, as shown more particularly in con- The sub-carriage which comprises the guideways 80 and end connecting bars 81 has a small toothed rack 83 on its under side at each end, and these racks mesh with and are driven by a pinion 84 mounted on the side members B of the frame. A shaft 85 extends transversely of the frame and carries two segmental gears 86 which mesh with and drive the pins 84, and this shaft extends through the frame at one side and carries at'its outer end a suitable hand wheel 87 or other device for con veniently rotating the segments 86. A segment 88 is also attached to the shaft 85 and has a series of notches 89 inits end. These notches cooperate with a roller 90 on a pivot arm 91, the roller 90 being yieldingly held in engagement with the segment hy'means of the spring 92. These notches correspond to the proper line spacing for the plate A and cooperate with the roller 91 to yieldingly hold the carriage in any position to which it is shifted for line spacing. The

shifting of the carriage K longitudinally,

that is transversely of the frame, for spacing of the letters or printing characters in the line thereof is accomplished by an escapement mechanism which is controlled by the mechanism which operated the die carrying wheels and not directly by the keys. On the'under side of the carriage is a long toothed rack 93 (see Figs. 5, 5, 9, 10,

12 and 13), which rack meshes with and drives a pinion 94. This pinion 94 is mounted upon a 95.which is journaled in a bearing 96 in the frame. Positioned in the front of the frame at one side and just below the carriage is a drum 9'? containing a spiral spring 98. This spring tends to rotate the drum in one direction. A long band or tape 99 (see Figs. 2, 5 and 5 is attached to the opposite end of the carriage and. is adapted to be wound around the drum 97. Thus the carriage is constantly under tension of the spring drum 98 which tends to move it in the direction of the arrow (Fig. 10). The shaft 95 which carries the pinion 94 also has a toothed escapement wheel 100. The tension which the spring drum 9? exerts upon the carriage constantly tends to shift it in the direction of the arrow 10) and thereby to rotate the pinion 94' and the escapement wheel 100. The escapementwheel, however, is normallvheld against rotation by a rocking lever which Is pivoted to the frame at 101. This lever rocks in s plane transverse to the plane in which the escapement wheel lies, and it has a fixed dog or tooth 102 at its upper end which engages oneof the teeth of the escapement wheel and prevents said wheel from rotation. This fixed tooth 102 is preferably substantially as thick as the escapement wheel and when the rocking lever M is rotated upon its pivot this tooth will be moved laterally out ofengagement with the teeth of the escapcment wheel, as shown in dotted lines in Fig. 9. The rocking lever M also carries a dog 104 which is pivoted at 105 upon said lever. A. spring 106 is also carried by the lever M and a es w constantly presses upon the lower arm of the pivot dog 104 to yieldingly hold the upper end of said dog some distance in advance of the tooth 102; this distance being substan-h tially the equivalent of one tooth on the escapement wheel 100. Thus when the lever M is rocked about its pivot and the tooth 102 moved laterally out of engagement with the tooth of the escapement wheel the yielding-dog 104 will enter into engagement with the escapement wheel one tooth indelvance of the escapement wheel tooth'which is engaged by the tooth 102, and as soon as the tooth 102 leaves the tooth of the escapement wheel theescapement wheel, being under tension by the spring drum 97, will rotate and carry with it the yielding dog 104. The lever M also has a shoulder 107 (see Fig. 10) which acts as a stop for the dog 104 to limit the movement thereof so that its forward face 108 will be flush with the forwaid face 109 of the dog 102 (see Figs. 10

and 13). When the escapement lever M is rotated in the other direction, that is, to the position shown in full lines in ig. 9, the yielding dog 104 will be moved laterally out of engagement with the tooth of the escapement wheel, and this same tooth of th escapement wheel will .be engaged by the I tooth 102 of the escapement lever. In other words, in this latter direction of rotation 6f the escapement lever M the escapemen-t wheel will not be permitted to rotate.

By this construction the carriage will shift a distance equal to one tooth on the escapement wheel and this distance governs the spacing of the lettersor printing cha r acti'ers which are stamped upon the printing plate A. In the structure shown, this escapemcnt, as before intimated, is actuated by the mechanism which actuates the die;

carrying wheel so as to be. independent of of this link passesthrough an opening: 111

in a rib 112 on the upper arm 72. -A'oo'uple oi-nuts 113 are'threaded on to this link110 and abut against the rib 112 of said Win72.

thus when the arm 72 is rotated by the movement of the thimble 18 and sleeve 19 in the direction to close the die-carrying wheels said lever will also rock the escapement lever M through the medium of the link so as to throw the escapement lever M in the position shown in full lines in Fig.

9. The rotation of said lever M in this direction, however, does not, as-above explained, permit the operation of the escapement wheel. When sald escapement lever,

however, is rotated in the reverse direction,

that is to the position shown in dotted lines in Fig. 9, the escapement wheel will, as

above explained, rotate one step. This'di-,

rection of rotation of the lever M corresponds to the opening movement of the diecarrying wheels. In other words, the carriage is not operated to shift the space of one letter until the die-carrying wheels have made their impression and commenced to open. The connection between'the link 110 and the arm 72 permits the arm 72 to return independently of the link 1 10, and in order that the escapement lever will be opera-ted or thrown to the position shown in dotted lines in Fig. 9,1 provide a spring 114 which presses upon said lever M and throws-itto said position when the arm 72 returns to its normal position. This the initial movement of the arm 72 during theclosing of the die-carrying wheels does not operate the escapement but merely places the ecsapement lever in condition so that when the die-carrying wheels upon and the ward portion of' the keyboard. This bar extends transversely across the entire keyboard and is mounted on two levers 116 adjacent the side members of the frame. These leve1's 116,. as shown in Fig. 5, are preferably pivoted upon the same shaft 49 on which the other key-levers are pivoted. Above the spacing levers 116 is a transverse shaft 117 which carries two levers 118, .these levers being positioned preferablydirectly above the levers 116. One arm of eaclr of said levers 118 is pivotally connected by a link 119 to'a lever 116. One of the levers 118 has another arm 120 which is connected by a. link 121 to an arm 122 on the escapement lever M. The link 121 passes through a hole in the arm 120 and hdsffi couple of it/sees nuts 123 whereby the arm 120 will actuate the link 121 and escapement lever M in one direction but will have a movement relative to said link 121 in the other direction. The

connections between the link 121 and the arm 120 and between the link 110 and the arm 74 permits the escapement to beeper ated either automatically or manually with out interference.

I also provide mechanism whereby the carriage may be manually released from the escapement and free to make a complete shift independent of the escapement. in order to do this 1 construct the escapement wheel so that it will rotate independently the shaft 95 on which it is mounted (see Figs. 9, 10, 11 and 12) and so that it will constitute one toothed member of a clutch. The other toothed member of the clutch is splined to rotate with. but to slide longitudinally of the shaft 95 and this clutch member is yieldingly held in engagementwith the escapement wheel clutch member by means of a spring 131 on the outer end of the shaft 95. member 130 the escapement wheel will be released from the shaft 95 and the carriage can then shift independently of the escapement wheel. I provide 'a 'key 132 in the keyboard for controlling this clutch. This key 132' is mounted on a key-lever 133 (Figs. 4, -5 and'll) which is pivoted on the keylever shaft 49 adjacent one side member of the frame, and a spring 134 yieldingly holds this lever in its proper position. A link 1535 is connected between the shift lever 133 and a short arm 136 on a transverse shaft 137.

' This shaft 137 (see Figs. 5 and 9) has another shortarm 138 adjacent the other side of the frame. which arm 138 is connected key 132 the clutch member 130 will be separated from the escapemcnt wheel clutch member andv the escapement wheel will thereby be disconnected from the shaft 95 leaving the carriage free to make a complete shift under the action of the spring drum 97.

I also provide a line-lock mechanism which operates to automatically lock the keys against depression when the end of a line is reached on the printing plate A. In Figs. 5 and 10 it will be seen that the spring drum 97 is mounted upon a shaft which issupported in two lug's 146 depending from. the frame of the machine. This shaft can ries a cam 147 on which rides a roller 148 mounted on a curved arm 149. The arm 149 is pivoted at 150 on the frame of the chine and its other end is pivotally connected' to a link 151 which extends downwardly and is connected tothe end of a By shifting the clutch n4 operation is being performed.

stop dog 152, the stop dog 152 being pivoted at 153 to the frame of the machine. stop dog 152 is adapted, under the control of the cam 14:9, to be dropped down into the path of a stop lug 15% carried on the link 6 which operated the universal bar 68. This stop lug is so positioned that when it engages the stop arm 152 it prevents the return of the universal bar and thereby locks up allof the keys againstdepression. The cam 147 is so proportioned that when the end of the line, which is being embossed on the plate A, is reached the low part of the cam 147 will be in position to permit the roller 148 and arm 149 to drop and also the stop arm 152 into the path of movement of the stop lug 154, thus preventing the return.

of the universal bar and the consequent locking up of the keys against further depression.

The. printing plate A is adapted to be held by the carriage 1*: while the embossing It-is nieces sary that the plate should be held quite firmly during the embossing operation but capable of being readily removed or inserted. I provide two gripping members 160 and161 (see Fig. 2) on the carriage K. These gripping membersliave grooves on their opposed edges for holding the printing plate by the edges thereof. The gripping member 161 is pivoted at 162 on the v carriage and a comparatively strong spring 163 yieldingly presses this gripping member into engagement with the edge of the plate A to grip the plate firmly between the two gripping members. The gripping member 161 has a cam surface 164 at one end which. engages a correspondingly shaped cam lug 165 on the frame when the carriage reaches its extreme left hand position. These cam surfaces cooperate to actuate the gripping member 161 and relieve the plate A of the pressure thereof so that the plate may be readily removed or inserted, as desired.
